Lionheart Day kicks off with a surprise as John Prince offers to bargain with Tressie over Sherwood's future; while Tressie and Prince negotiate, Robyn starts to suspect things are not what they seem when Guy Gisbourne returns to crash the party.

The sheriff imprisons Robyn and her friends in a black site, determined to uncover The Hood by any means necessary; Prince pressures the mayor; Robyn puts her faith in a dowdy social worker who seems completely out of her depth.

With Prince's purchase of Sherwood complete, the Sheriff gives Robyn and her friends mere hours to evacuate; instead, Robyn joins forces with Tressie, Jill and her neighbors to make a final stand against the Sheriff.
